Xv: free tearing on textured video
Add an Xv attribute XV_SYNC_TO_VBLANK which has three values -1(auto), 0(off) and 1(on) to control whether textured adapter synchronizes the screen update to the vblank. The default value is -1(auto).

+.SH TEXTURED VIDEO ATTRIBUTES
+The driver supports the following X11 Xv attributes for Textured Video.
+You can use the "xvattr" tool to query/set those attributes at runtime.

+.SS "XV_SYNC_TO_VBLANK"
+XV_SYNC_TO_VBLANK is used to control whether textured adapter synchronizes
+the screen update to the vblank to eliminate tearing. It has three
+values 'auto'(-1), 'off'(0) and 'auto'(1). 'off' means never sync, 'on' means
+always sync, no matter what size, and 'auto' means sync if the Xv image is
+more than quarter of the pixels on the screen. The default is 'auto'(-1).
